Decaying Fescue is a brown colored grass powered by both Nature and Dark Nature energies. This unusual combination of two anti-thesis energies came about from the change that swept Melriths Hunger. It was nature's way of adapting to the conditions.
At a low level, Decaying Fescue is a coexistence of two anti-thesis energies. It could have been the start of the condition of Emeldimir. Three forests, each patched with stretches of verdant growth, yet surrounded by a sea of decay. It is like the forest is being managed. The fey keep enough alive so that it does not become another Melriths Hunger.
Decaying Fescue is used to make straight blades. They are as hard as steel, and both fireproof and rustproof. When deemed broken, their is a 50% chance that this means the weapon only needs to be straighten out. When enchanted, plant growth spells can be applied to give the weapon a more refined shape.
